Researchers from the Swiss Federal Laboratories for Materials Testing and Research ( Empa<\/a> ), the University of Economics and Engineering of the Canton of Vaud<\/a> and the Swiss Federal Institute of Technology in Lausanne ( EPFL<\/a> ) have jointly developed new rail pads. These components are mostly made of elastic plastic and are stuck between rails and concrete sleepers, as Empa explains in a press release<\/a> . They are used to protect rails.<\/p>\n

However, existing rail pads have limitations. Especially if the protection of the rails is greatly increased, this leads to more noise pollution at the same time. The researchers now want to solve this challenge. After several tests in the laboratory, a part with more than 50 percent polyisobutylene (PIB) content, embedded in a shell made of a harder ethylene vinyl acetate (EVA) plastic, proved to be the most effective option. At the same time, it can reduce railway noise and protect the rails.<\/p>\n

In a next step, the new rail pads are to be tested on a railway line in Nottwil in March. \u201cThese rail pads are easy to make. We will need almost 400 units for the 100-metre stretch,\u201d explains Bart van Damme from Empa’s Acoustics and Noise Reduction department. That is why a company is already on board that will take over the manufacture of the components that have already been patented.<\/p>\n","protected":false},"excerpt":{"rendered":"
